Abstract

The invention discloses a track control type gravity center adjustable polishing mechanism and a polishing method. The polishing mechanism comprises a polishing disc, a power transmission mechanism, a gravity center adjusting mechanism and a supporting mechanism. The power transmission mechanism comprises a motor and a power main shaft, and the power main shaft is flexibly connected with the polishing disc. The gravity center adjusting mechanism comprises a track plate, a swing plate and a pressure applying mechanism. The track plate is fixed, and a track groove is formed in the track plate; The swing plate is coupled outside the power main shaft and is provided with a convex block matched with the track groove. The pressure applying mechanism is located between the swing plate and the polishing disc and used for transmitting swing pressure of the swing plate to the polishing disc. According to the track control type gravity center adjustable polishing disc mechanism and the polishing method thereof, the track groove of the track plate is utilized, the edge effect can be reduced by adjusting the gravity center of the polishing disc, and the characteristics of being easy to operate, high in practicability, capable of achieving automatic control and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of optical element finishing, and relates to a polishing tool and a polishing method for precise polishing of an optical element, in particular to a track-controlled center-of-gravity adjustable polishing mechanism and a polishing method. Background technique [0002] At present, in the field of optical component finishing technology, whether it is classical processing or computer controlled surface shaping technology (CCOS), when processing the edge area of ​​​​the workpiece, due to the reduction of the contact area (because the polishing disc part protrudes from the workpiece) When the stress remains constant, the contact pressure increases, which leads to an increase in the removal amount of the edge of the workpiece and the edge effect of "collapse". This edge effect will seriously hinder the convergence of the workpiece surface shape error, and even reduce the effective diameter of the workpiece . [0...
